Wikipedia Trails: From Sioux to Source Rock

This week I decided to start my trail on the Sioux since that is the native american reading I chose. I learned that many of the Sioux Indians lived in north central united states area like present day North Dakota. Being the Energy focus person I am, I then clicked on the Bakken Formation which is one of the U.S.'s largest oil producing basins. Lastly, I clicked on source rock to fact check Wikipedia's knowledge over hydrocarbon generation. It looked on par to me. Thanks for reading.
